Error with root web.config - Network Solutions setup

We have a custom build site that loads products from the database, does url rewriting,etc... We recently moved to Network Solutions hosting and are now wanting to do some blogging and had the NS account install BlogEngine.NET into a folder
called 'toolkit'. Now when we go to that folder (http://www.domain.com/toolkit/) an error arises. When I changed the /toolkit/web.config to be <customErrors mode="Off" /> the error it displays is:

A different forum found the solution. Since my root web.config has httpmodule and so does the subfolder, to get the subfolder to not use the root you have to enter the <clear /> tag in the subfolder httpmodule section. I was
able to see the site after I entered this. Now I just can see where you make a post.
